Design principle of vacuum bottle cosmetics

Vacuum bottle is a container that can insulate the gas from the outside temperature or a container to keep off the outside bacteria.

The contents of the vacuum bottle can be completely isolated from the air, preventing products from oxidation, bacteria and bacteria because of exposure to air, and promoting product files with its high-tech concept. The vacuum bottle on the prevailing market is composed of a cylinder and a piston ellipsoid placed at the bottom of the container. Its design principle is to use the spring contraction force, and does not let the air enter the bottle, causes the vacuum condition, but uses the atmospheric pressure to push the piston of the bottle bottom to advance. But because of the spring force and the atmospheric pressure can not be given enough power, so the piston is not with the bottle wall attached tightly, otherwise the piston will be due to the resistance is too large to rise ahead; conversely, if you want to move forward and prone to piston leakage, so the vacuum bottle manufacturers of professional requirements are very high.

The introduction of vacuum bottles conforms to the latest development trend of skin care products, and can effectively protect the fresh quality of products. However, because of the complex structure and high cost of vacuum bottle, the use of vacuum bottle packaging is limited to a limited range of products, and can not be spread out in the market to meet the needs of different levels of skin care products packaging.

Here in Hangzhou Trading Company Limited in the importance of skin care and skin care product packaging protective and decorative, began to focus on the development of functional skin care product packaging, the product of "fresh" and "natural" and "preservative free" concept worthy of the name.
